I think sound and bass performance on note 10 plus is a bit lower I dont know is it the software but my galaxy buds and type-C earphones sounds way better on note 9 and other phones.
yes really disappointed atleast expecting they improve the audio output with software updates.even camera quality is not as good as one flagship phone should have.
famous tech gigs receives them for free for reviewing and once it is launched they can post it on internet which helps the device promotion for which they also get paid a good amount
